To all whom it may concern Be it known that I, THOMAS citizen of the United States,

UNKs, a

of Ohio, have invented new and provements in Operating Means for Washof which the follovvingis a specification.

This invention relates to certain new and useful improvements in operating means for washing machines, and has for its primary object, the provision of improved means, "of simple and economical construction, for imparting combined vertical 'reciprocatory, and alternating rotary movement to the tub.

In the drawings: Figure 1 is a top plan view of the invention; Fig. 2 is a side ele vation; Fig. 3 is a section takenon the line 33 of Fig. 2; and Fig. is a front eleva tion, the tub and rub board beingomitted.

In proceedingin accordance with the invention, a frame is provided which includes a horizontal U-bar l, and end standards 2, the latter having the rub-board 3, suitably connected thereto, as well as the wringerboard support 4.

Y A disk or plate 5, has a stem 6, which depends therefrom and extends through an aperture provided therefor in the U-bar 1, a spring 7, encircling the lower portion of the stem so as to exert downward tension on the disk. The tub T seats on the upper face of the plate 5, and receives the rub-boardonits interior.

Ashort shaft 8 extendsthrough provided therefor in the sides of the U-bar 1, and supports a pair of cams 9 at its opposite ends. The cams are reversely arranged,

or disposed, and have frictional contact with the under face of the disk or plate 5, soas to alternately rotate or move the disk clockwise and counterclockwise. Each cam 9, has

' a stem or shank 10, which depends therefrom, the free lower ends of the shanks 10,

being pivotally connected to links 11, the links in turn being pivotally connected to cranks 12 formed on ashaft 13, the cranks being arranged to extend in opposite-direc-' tions, as depicted in Figs; 2 and 8, of the drawings. A comparatively large gear 14,

is secured to the shaft 13 so as to rotate the.

latter, the gear 14, being in mesh with a pinion 15, that is keyed to a short shaft 16, which is j ournaled in the frame, and has the fly or balance wheel 17, connected thereto.

An operating lever 18, is in pivotal conneci I v I v I I Specification of Letters Patent.

tionwith the frame, andhas a link19,.piv-- ote'd thereto, largegear 14:,

the link being pivoted tothe through the oscillatory movement of the cams 9. The

'cams9, which frictionally bear against the the plate being due to the opposite disposition of the cams 9, which oscillate in oppodisk or plate 5, are-devoid of teeth, and are possessed of smooth surfaces, which enable inexpensive production of the parts.

. Bydirectly connecting each cam to the crank shaft, thelatter effects a direct operation of the cams, and in addition by providing the cams with comparatively long shanks, greater leverage is obtained which enablesthe cams to raise the disk with the expenditure of less power by the operator. What is claimed is: I

- 1. In combination with a support adapted to have vertical and rotatable movement, a

cranks thereon, disposed cams each secured on the second shaft ha'ving comparatively long depending said camsa-lternately engaging the tical reciprocatory and alternating rotary motion to the support, links directly con-' fnected to the respective cranks and shanks,

so that oscillatorymovement] manually imparted to the lever- 18, will,

medium of the link 1 9, rotate The cams, as Well as the 7.5

and means to effect rotation ofthefirst men- .ti'oned shaft.

02. In combination with a vertically movable support, a pair of oppositely disposed cams having depending shanks, said cams alternately rotating the-support by engaging theunder face ofthe support, and means connected to the shanks of the cams to .oscil:

late the latter in opposite directions.

In combination with a vertically movfor-operating same, and a crankshaft to which each of saidmeans is pivoted.

In combination with a vertically movable and rotatable support, a pair of rocking cams which engage with the under face of the support, and means to impart oscillatory movement to the cams in opposite directions to impart vertical reciprocatory and alternating rotary motion to the supp 5. In combination with a vertically movable support, a rotatable member, means to impart continuous rotary movement to said member, means to impart alternating rotary and vertical reciprocatory movement to said support, and means connecting the rotatable member with said first named means whereby the latter is given oscillatory movement.

6. In combination with a frame, a shaft supported by the frame and having oppositely disposed cranks thereon, a second shaft journaled in the frame and having a pair of oppositely disposed cams thereon, links pivotally connecting the cranks and cams, a supporting disk having a depending stem rotatably and slidably supported in the frame, means for yieldably holding said disk in its lowermost position, and means for rotating the crank shaft for oscillating the cams, whereby the same alternately engage the supporting disk to impart vertical anoll oscillatory movement to the supporting dis In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
